l The invention relates to vide a device that includes a casing forhousing several rolls or spools of adhesive tape or the 4like ofvariousl widths, the tape being removable from any one of the rolls andout in strips of any desired lengths, in an easy and expeditious Anotherobject er the yinvernaen is to prende va tape holding and cutting devicein which the cutting means thereof is automatic in its action, that is,when the desired length of tape' is reu lmoved from the roll, a slightjerk on the length removed will render the cutting means active andcause the same to sever the tape', with the result it is possible forthe user to remove a strip frein the roll, with oney hand, While theother hand is beingk used for holding a bandage or for Ianother purpose.

' A further object of the invention is the pio- "vision of a device ofthis character, wherein' the mechanism for holding the tape and thecutting of the saine is confinedy within a casing, so that it cannotcollect' dirt or dust,-whi1e the rolls of tape will be protected fromthevveather elements.

'A still further object of the inventionl is the :provision of a deviceof this character, wherein a free portion of the tape can be readily andeasily grasped, when it is desired toI remove a length' thereof` from aroll withinthe casing of v,

the device.

Astil'l further object of the invention is the provision of a device ofthisA character, wherein the cutting means is guarded against" any'possibility of the user cutting 'or injuring' the hands, lduring theprocess of' removing' and cutting the 'tape'.

A still further object' of the invention is the provision of a device ofthis character, wliich'is simple in construction, thoroughly reliableand efficient in operation, strong', durable, susceptible .of being hungfrom a support, readily and; easily operated,v and` inexpensive tomanufacture and install.

With these and other objects in view, the invention consists in thefeatures of` construction, combination and arrangement of parts as will.be-hereinafter more fully described, illustrated ln the accompanyingdrawings, Which-disclose the preferred embodiment of the invention andpointed out in the claims hereunto appended.

--fs'i'rrrilar Yrei'errance characters indicate corresponding partstriroughout tlie several views` in 'the drawings. e

Referring to the drawings detail, it should se noted that the devi-ce'constituting the present invention includes a substantially cylindricalcasing fc Having end walls fr and a portion of the cylindrical Wall,Ais'irr fact'- a door l2 hinged as at r3 for vertical swinging movement;and is supported in vem open positiorrby a break-@jointed prop orbracket Hl whereby a longitudinally disposed openingor mouth lli1 isprovided iiisa'i'd Through this' mouthitis discut in' a manner presentlydescribed.

y The end walls Hf have fixed thereto andestendi'ng centrally andinwardly therefrom, studs Ie providing trunnrons carried by a pair of'spaced parailelracketsl1 outside or the casing mi, with tire casingdisposed thereletween, as snpwn in Figures ll, 2'` and 3L ofthedrat'vifngs. Thebrackets li? increasei-'lii1 Width tdvlardtlf'ie rareds'thref and@ termed. the rear' ends' and extending outwardly at" right'angles thereto are attaching ears $181, the latter havingl openingstherein for receiving screws`A on other'fastening means5 Bit for securing' .thel brackets to* a Walle or other support; as

indicated in said= Figures 1, 2. andl 3.

The end walls Il also have lugs 20 secu-red to "and extending laterallytherefrom for engaging .with stops 2 t' cut'l andi struck inwardly fromhthe trunnions blades 38.

fof the cutter bar 31. arcuate slot 4I extending alongthe lengththerebrackets I1 adjacent to the rear portions thereof for disposal inthe path of the lugs 20, to limit rearward movement of the casing to itsnormal position in a rotary direction, as best seen in Figure 1 of thedrawings.

Secured within the casing I0, in the form shown, are two disk-likepartitions 22 and 23, respectively, the partitions each including a pairof walls having peripheral iianges formed thereon and directed towardeach other for disposal in engagement, as shown in Figure 4, of thedrawmgs. the ends of the casing to provide a wide space or compartment24, and the partition 23 is arranged adjacent to one end wall to providean in- The partition 22 is arranged midway of termediate compartment orspace 25, and an I end compartment or space 26. Each of the spaces orcompartments is adapted to receive a horizontally disposed upper andlower guide rolls or rods 44 and 45, respectively, between which a slotis provided through which the tape B is threaded, this rack 43 beingmade fast and in an upstanding position in confronting relation to themouth I5, through which the severed tape is acquired.

The casing I0 at the end walls II thereof and exteriorly of the same,has a pair of coiled springs 46 attached thereto, these being alsoattached to the brackets I1, rearwardly of the said casing, and suchsprings urge and hold the latter in its normal position.

In the operation of the device, it might be mentioned that a length oftape is rst removed from the roll and the latter is then placed withinits compartment. The length or portion which is indicated at C isarranged for disposal through roll A of adhesive tape B, the rolls beingvariable in widths in accordance with that of the compartments orspaces, that is the compartment 24 is for a roll or spool of two inchtape, thercompartment 25 for a roll of one inch tape, and thecompartment 26 for a roll of one-half inch tape. However, the device canbe made from only one roll or spool of tape of any width or for morethan three rolls, as will be apparent.

Within the casing I0, near the end walls II thereof, and keyed orsplined at 21 to the studs or curved arms 28 having at their lower` endspivots 29, connecting thereto upright rocking levers 30 .for operatingthe cutting means and guard therefor. These levers 30 at their lowerends are pivoted at 3l to short links 32, which are also pivoted at 33to the end walls Il below the studs or `trunnions I6, as best shown inFigure 5 of the drawings. The upper ends of the levers 30 are rearwardlydirected and secured to and extending inwardly and laterally therefromare pins 34.. The cutting means includes a pair of substantially arcuateshaped arms 35 disposed upon opposite ends of the studs or trunnions I6,which constitute pivots therefor, these arms 35 being directed ears 36which have secured thereto and j bridging the same a cutter bar 31, thelatter being formed with substantially triangular shaped There are inthis instance three blades 38, one for each compartment or space, v andeach blade is of` a length co-extensive with the width of its companioncompartment, as best shown in Figures 2 and 4 of the drawings, with itsbeveled knife edge directed toward the compartment, as will be apparent.

The guard for the cutting means is of enlongated substantially U-shape,4to provide limbs 39 that have their rear ends curved downwardly and arelikewise pivotally mounted on the studs ,or trunnions I6, for disposalof the bight portion 40 of such-"guard adjacent to and in advance Thelimbs` 39-each has an of, while the arms 35, each has an oppositely po-'sitioned arcuate shaped slot 42 arranged therein each other, andmounted in the slots are the pins 34 that are secured to the outer endsof the leivers 30. 1 AWithin the casing I0 at the delivery side of thedevice is a rack 43 having the closelyarranfged 1,

I6 are forwardly and downwardly.4

vand pulled outwardly in substantially a horizontal plane, which resultsin the tape being unwound from the roll. When the desired length isreached, the portion C is then given a quick downward movement or jerk.That movement results in the casing I0 partially rotating forwardlyagainst the action of the springs 46. The forward rotation of the casingI0 moves the upper ends of the levers 3B forwardly, as shown in Figure 5of the drawings, and such movement causes the pins 34 to ride forwardlyin the slots 4I and 42 for rocking the cutting means and the guard, theybeing lowered simultaneously, but due to the fact that the arcuate slots42 are upwardly directed, the cutter bar will move ahead of the bightportion of the guard adjacent to the end of the downstroke of thelatter, and such movement of the cutter bar will cause the blade tosever the tape, as will be apparent upon inspection of Figure 5. Afterthe strip has been severed, a relatively long portion remains to begrasped when it is desired to remove and sever a subsequent strip oftape from the roll.
